Description of the Invention: [Technical Field] The present invention relates to a flexible circuit board, and more particularly to a bonding apparatus for a tape-type film material. [Previous Technology] Flexible printed circuit boards have been widely used in notebook computers, mobile phones, personal digital assistants, and digital phase Φ 因 because of their good flexibility. As consumer electronics are moving toward thinner and lighter, flexible printed circuit boards are also moving toward the use of thinner and lighter polyimide laminates. The conventional method for manufacturing a flexible printed circuit board mainly comprises laminating a copper foil on the surface of the polyfluorene layer, and forming a polytheneimide copper-clad laminate by hot rolling. Due to the manufacturing process of the polyimide foil copper laminate, it must pass through a high temperature oven and its temperature is higher than 35 〇〇c to carry out hot rolling & «film material, such as polyimine layer or copper. The foil layer, when it is almost exhausted, • The oven temperature must be lowered to replace the new film. After the refueling of the new film material is completed, the temperature is re-heated to carry out the process of the continuous film rolling process. Therefore, as long as any roll film is used up, #The oven must be repeated for cooling and lifting. However, this rise/lower temperature process is not only time consuming, but also difficult to operate. Furthermore, after the refueling is completed, the subsequent process can be carried out because the temperature in the oven must be raised to the temperature of the hot rolling press, so the film material located in the oven during this period is not thermally stable due to its thermal stability. It is too good to use 'and thus waste a lot of film. In view of this, the position of the roller set in the accumulator is usually adjusted to 5 1316832, on the one hand, the conveying speed of the film to the high temperature oven is maintained, and on the other hand, the end of the film to be depleted is placed on a carrying platform. In order to facilitate the bonding work of the two film materials. Referring to the drawings, a schematic cross-sectional view of a conventional tape-and-reel film is shown. First, the two membrane materials 1〇〇, 1〇2 are transported to the loading platform, and then the cutting end 101 of the first output film 1 is cut by a cutting device 101, that is, the film material which is quickly depleted is 1〇〇. Cut off. Next, thermoplastic polyimides 104a, 104b are placed on both ends of the two films 1 〇〇, 1 〇 2 to be joined, and then placed on the thermoplastic polyimide 〇 4a, 1 〇 4b. A copper sheet 106. Then, the copper sheet 1〇6, the thermoplastic polyimide 〇4a, 1〇4b and the two film materials 1〇〇, 1〇2 are thermocompressed to complete the connection of the two film materials 1〇〇 and 1〇2. . In this way, in the case of no-stop, the two membrane materials can be joined together. However, one of the difficulties of the above method is that, since the method is to cut off the rapidly depleted film material 1 00 and the new supplement The overlap of the film material 丨〇2 maintains a proper distance between the two film materials 100 and 102; then, two thermoplastic polyimides are bonded to the joints of the two film materials 1 and 102 at both ends. After the crucibles 4a and 104, the copper sheets 106 are used to join the two films 100 and 1〇2. Therefore, the work of bonding the film 100, 1 〇 2 with the copper sheet 106 has two joints, and the film materials 100 and 102 are bonded, respectively. If the film materials 1〇〇 and 1〇2 fail to maintain an appropriate distance or even overlap, then the steel 106 is bonded to the same film to cause failure. In addition, the relative positions between the copper sheets 106 and the film materials 100 and 102 must be aligned, and the positions between the film materials 1 and 2 must also be aligned. Therefore, based on the requirements of the positional alignment between the three materials, , the problem between the copper sheet and the film material or between the film material and the film material. Once there is a precise alignment between the two, it will lead to the failure of the subsequent lamination process, which in turn will affect the yield of 1316832. Furthermore, since the above method uses a copper sheet and two sheets of thermoplastic polyamidimide, not only the material cost is greatly increased, but also the operation time required is long and the operation convenience is not high. There is therefore a need for an improved method and apparatus for joining tape and reel film materials to solve the above problems.

[Embodiment] The present invention provides a bonding device for a tape-type film material and a method thereof, which are applied to a manufacturing-flexible circuit board, so that the film material can be directly utilized in a state of no downtime when the film material is used up. The hot press process is used to join the two film materials, and the film material that is output first is cut to complete the joining of the two film materials. The new tape-and-roll film joining process uses a single-point bonding method to join the old and new film materials, and the thermoplastic film of the old film material is bonded to the end of the old film material, and then heat-pressed with the new film material. If the upper or lower layer of the film is a thermoplastic polyimide film, the existing thermoplastic film can be directly pressed against the old film using the existing thermoplastic film. The new tape-and-roll film joining process requires only alignment of new and old film materials and eliminates the need for copper n, which simplifies the process and reduces the cost of 9 1316832 and improves yield.
